WlAfil-HNE FOR APPLYING COLLARS TO LAMPS.

SPECIFICATION forming part of Letters Patent No. 642,307, dated January 30, 1900.

Application filed November 21, 1899. $erial No. 737,758. (No model.)

To all whom it may concern:

Be it known that I, PHILLIP EBELING, a citizen of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented or discovered certain new and useful Improvements in Machines for Applying Collars to Lamps, &c., of which improvements the following is a specification. The invention described herein relates to certain improvements in mechanismfor applying metal collars to the necks of lamps and other like articles.

It has heretofore been the practice to attach collars to the necks of lamps, pitchers, &c., by means of plaster-of-paris or other suitable cement. This method is objectionable, as the cement is so injuriously affected by the contents of the vessel that the collars become loosened. It has been attempted to avoid the use of cement by spinning the collars on the lamp-necks; butit has not been possible to form a tight joint between the neck and collar by this method.

The invention described herein has for its object the construction and arrangement of mechanism whereby collars having an internal diameter slightly smaller than the external diameter of the neck of the lamp or other article maybe forced onto such neck, whereby the collar is caused to embrace the neck so tightly as to form a hermetic joint and to render it practically impossible to remove the collar without rupture or the breaking of the neck.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of my improved machine on an enlarged scale. Figs. 2 and 3 are sectional elevations showing the operation of applying collars to lamp-necks.

In the practice of my invention a mandrel or rod 1 is suspended from the frame 2, and on this mandrel is mounted a sleeve 3, having a head or enlargement 4 at its lower end. The lower ends of links 5 are pivotally connected to the sleeve, while their upper ends are connected to the arms 6 of the operating-lever 7, said arms passing on opposite sides of the mandrel. The lower end of the mandrel is slotted for the reception of the supporting-bar or anvil 8, which is pivotally mounted in said slot and has one end so weighted as to normally hang within the slot, as shown in Fig. 2. An axial passage is formed in the mandrel for the reception of the shifting pin 9, which has its upper end attached to the cross'arm 10. The ends of this arm extend out through slots 11 11, formed in the mandrel and sleeve, respectively, and are connected to one end of springs 12, which have their opposite ends connected to the sleeve 3.

In applying collars to lamps a collar 13 is placed on the neck 14 of the lamp, as shown in Fig. 2. The lamp is then raised so that the lower end of the mandrel, which is preferably made of an external diameter slightly less than the internal diameter of the neck and threaded portion of the collar, will project into the lamp sufficiently far to permit of the supporting-bar or anvil being turned to a position transverse of the neck of the lamp. The sleeve is then moved down along the mandrel by the lever 7. During the first part of this movement the shifting pin 9 will strike against the inclined edge of the anvil 8 and shift it to position across the neck of the lamp, so that its ends will project under portions of the lamp-body adjacent to the neck and support the lamp during the subsequent operation. As the pin 9 is connected to the sleeve by springs 12, the latter will yield during further downward movement of the sleeve, permitting the pin to remain stationary. By the continued downward movement of the sleeve its head at will bear upon the end of the collar 13 and press it home on the neck. The sleeve is then raised, and during its final upward movement the pin 9 is drawn away from the anvil. The lamp is then slightly raised along the mandrel to permit the anvil to turn to parallelism with the mandrel, so that the lamp can he slid off the mandrel.

I claim herein as my invention- 1. I11 a machine for applying collars to lamps, the combination of an anvil or supporting-barinsertible through the neck of the lamp, and a pressing-head movable toward and from the anvil, substantially as set forth.

2. In a machine for applying collars to IO ed, and pivotally mounted on the mandrel, a

shifting pin and a sleeve having a pressinghead movably mounted on the mandrel, and a spring connection between the sleeve and shifting pin, substantially as set forth.

In testimony whereof I have hereunto set 15 my hand.

PHILLIP EBELING. Vitnesses:
